Please note that the majority of our items are vintage and therefore have tales to tell unless stated otherwise. Therefore, please look at pictures, descriptions and measurements provided as they give you the best idea of the story this item has to tell.
* Please note that when you buy a vintage product, the dimensions may vary slightly from a new one depending on previous care and storage.
Q: What is the Omega Seamaster 300M 36mm offered here? A: It’s a vintage mid‑size Seamaster Diver from Omega with a 36mm stainless‑steel case and bracelet, the signature black wave dial with luminous hands/markers, a unidirectional rotating bezel, and a date at 3 o’clock. Swiss‑made, it blends everyday wearability with classic dive‑watch design from the mid‑2000s era.
Q: Which movement does this mid‑size 300M typically use? A: Mid‑2000s 36mm Seamaster 300M models were produced in both automatic (often Omega Calibre 1120, ~44‑hour power reserve) and Swiss quartz (commonly Calibre 1538). We can confirm the exact movement in this specific watch on request and share detailed photos if needed.
Q: Is it water‑resistant and can I swim with it? A: When new, the Seamaster 300M was rated to 300 metres. With vintage/pre‑owned watches, water resistance cannot be guaranteed without recent servicing and pressure testing. If you plan to swim, have the gaskets inspected/replaced and the watch professionally tested first. Always keep the crown fully screwed down before any contact with water, and rinse with fresh water after sea exposure.
Q: How do I set the time and date safely? A: Unscrew the crown anti‑clockwise. Position 1: (automatic only) wind ~20–40 turns if the watch has stopped. Position 2: quickset the date. Position 3: set the time. Avoid changing the date between roughly 8pm and 2am. When finished, push the crown in and screw it down firmly. If your watch is quartz, no winding is required; the date/time setting steps are otherwise the same.
Q: What crystal and dial features does it have? A: Most Seamaster 300M models from this era feature a scratch‑resistant sapphire crystal. The dial is the iconic black wave pattern with luminous markers and skeletonised hands for strong legibility in low light. We can confirm the crystal type on this exact piece upon request.
Q: How should I use and care for the bezel? A: The unidirectional bezel is for timing elapsed minutes (e.g., dives or cooking). Rotate it counter‑clockwise only; never force it clockwise. After saltwater use, rinse the watch and gently rotate the bezel to clear any debris. Avoid hard knocks, as bezel inserts can mark or scratch on vintage pieces.
Q: Will the 36mm size fit my wrist, and can the bracelet be resized? A: The bracelet length is approximately 18cm as listed. 36mm is a versatile mid‑size that suits many small‑to‑medium wrists and wears well unisex depending on preference. We can size the bracelet before dispatch; additional links may be sourced subject to availability—share your wrist measurement and we’ll advise.
Q: Does it have a helium escape valve, and do I need it? A: Many Seamaster 300M models feature a helium escape valve at 10 o’clock, designed for professional saturation diving. Recreational swimmers and divers do not need to use it; keep it closed. If you’d like us to confirm whether this specific watch has the valve, we’ll verify from detailed photos.
Q: What accuracy and service interval should I expect? A: A healthy automatic Seamaster typically runs within a few seconds per day; quartz versions within a few seconds per month. As a guide, service mechanical movements every ~5–8 years (or sooner if accuracy/water resistance is a concern). Quartz batteries often last ~2–3 years; replace the cell and inspect seals at the same time. Keep the watch away from strong magnets and extreme heat.
Q: What is included, and do you guarantee authenticity? A: This listing is delivered with no accessories unless stated otherwise. A Retro Tale rigorously authenticates every item and guarantees 100% originality. All watches include a 12‑month mechanical guarantee. We offer free, fully insured DHL shipping, a 14‑day return policy, and 0% customs fees for EU buyers; contact us for any specific delivery or warranty questions.
